Abstract
A diaphragm-type carburetor has a high speed adjusting needle and a low speed/idle adjusting needle which are independently supplied with fuel from the metering chamber. The path for fuel to the low speed/idle needle has a valve which is controlled by the angular position of the throttle shaft such that when the throttle shutter is closed the valve is open whereas when the throttle shutter is open the valve is closed.
